" coated with iron oxide powder using lacquer as glue. "

Hi Ecca, like I mentioned earlier. it looks like lacquer coating on my Schaller drum. I bet they mixed the oxide with the lacquer and sprayed it on. If I could find a drum for my unit, i'd experiment spraying one just to see if it works. Have a great day. Scott

I have no clue exactly what people am on about with these drums
I do know that old video players have a little drum inside them, don't know if you could use these for something in your build maybe?
Another question....Could a video player be used as an echo system if modified in some way? I had a video player that had 4 heads on it, don't know if that would make any difference or not

You would have to Google that Ryan, I heard of a video recorder being used for sound recording once upon a time but I don't think anything came of it.....

Thanks for that ecca, it's not something i would want to do, just wondered if anyone had done anything like that. More out of curiosity than anything else.
Cheers

Yes, VCR's have drums, but they dont rotate like the drums in the Meazzis and Binsons.
The drum is angled and contains video heads which scan the tape as it moves over the drum.
The head speed combined with that of the tape speed allow the very high writing/reading speeds which are required to resolve the exceptionally high frequencies used in video reproduction.
This leads to a roughly equivilant tape speed of around 15 feet per second.

Do I want one ? If what I heard today translates through a band mix to the audience - YES !

And that is, of course, the whole point. Sooner or later we can all get the sound we want at home. Getting it on stage with the other guys adding their bits, plus a hall acoustic, is a whole different ball game. Anyone who can crack that can take a well deserved bow.

Great !

Now you say the same as I did since years in this forum. It`s not easy to bring a very good
Shadows sound on stage with the same stuff as Hank used in the 60`s - guitar - amp - echo !

Appropo Poulsen and the first ribbon tapes. My dad had one of these, one of the first commercial tape recorders in the UK.
It used paper tapes coated with the oxide.
It ran at 7 1/2 IPS and was a full track recorder.

All interesting stuff.....
I think I will have a crack at coating a drum with ferric oxide, I've ordered some.
The wire wound as per the Binson looks to be fraught with hazard. For starters it's only .1mm dia.( 4 thousands of an inch approx. ) The winding of that onto a drum poses no problem but the grinding of it does. It would have to be very tightly wrapped and then , assuming you grind it OK you're then left with a wire thickness of approx. .05mm ( 2 thou )

I'm not sure about the drum yet, I don't want to unduly spend much money on something that may not work. It could be made of anything really, only the outer diameter must not be magnetic other than the oxide coating. There must be sufficient mass in order to reduce wow and flutter. I've ordered a direct drive motor from a record player to simplify the rotation of it, ( cheap !) no belts or idler wheels and a flywheel will be included somewhere..

.... and that's as far as I've got.
